To investigate responses of Glycyrrhiza glabra var. glabra and G. glabra var. glandulifera to molybdenum and salicylic acid, we measured four stress biochemical parameters: anthocyanin, nitric acid, glycyrrhizic acid and peroxidase activity in callus tissues. Callus tissues obtained from seedlings root cultures were treated by 60 mg. l-1 molybdenum and 5 µM salicylic acid alone or together for...

Mixed ligand complexes of general formula (ML)2. H2BQ, where M = Li, Na or K, L = deprotonated salicylic acid, acetylsalicyilc acid or 2-hydroxy-3-napthoic acid; H2BQ = 2, 5idhydroxybenzoquinone have been synthesized and characteriszed. The infrared studies indicate the presence of intramolecular hydrogen bonding in the complexes, whcih may be one of the factors for stabilizing them.

Abstract In this work, two catalysts based on polyethylene glycol (PEG) containing sulfonic acid group and the −COOH of citric (CA) were synthesized. Characterization −SO 3 H functionalized PEG has been carried out using FT–IR. The acidity PEG–SO PEG–CA explored to investigate their catalytic efficiency towards eco-friendly production methyl salicylate via esterification salicylic methanol as a...

For studies on the lysosome-stabilizing effect of D-glucaric acid derivatives which have been found to have anti-inflammatory effect, the available and soluble enzyme activities of acid phosphatase of rat liver lysosomes were determined. Saliployed as standards. Lysosomes were incubated with drugs under specific conditions which allowed the data on the stabilizing activity of the drugs to be re...

The activation of programmed cell death (PCD) is often a result of complex signalling pathways whose relationship and intersection are not well understood. We recently described a PCD root hair assay and proposed that it could be used to rapidly screen genetic or pharmacological modulators of PCD. To further assess the applicability of the root hair assay for studying multiple signalling pathwa...

This paper presents the efficacy of PGPR (Azospirillum and Pseudomonas) and its modulation by salicylic acid. Two hybrids of sunflower (Hysun and Parsun) were inoculated with Azospirillum spp. and Pseudomonas spp. prior to sowing. Salt stress (20 dSm) was applied 28 d after sowing followed by foliar spray of salicylic acid (100 μM) after 4 h of salt treatment. Azospirillum and Pseudomonas inocu...

Salicylic acid, salicyluric acid, and gentisic acid in plasma are specifically quantitated (ultraviolet detection at 313 nm) with an octadecyl silane reversed-phase chromatographic column by peak-height determination or by peak-height ratios (internal standard, o-methoxybenzoic acid). Sample preparation requires addition of an equal volume of methyl cyanide (with or without the internal standar...
